U.S. electricity generation by energy source



What is U.S. electricity generation by energy source?

In 2016, about 4.08 trillion kilowatthours (kWh) of electricitywere generated at utility-scale facilities in the United States.2  About 65% of this electricity generation was from fossil fuels (coal, natural gas, petroleum, and other gases), about 20% was from nuclear energy, and about 15% was from renewable energy sources. The U.S. Energy Information Administration (EIA) estimates that an additional 19 billion kWh (or about 0.02 trillion kWh) of electricity generation was from small-scale solar photovoltaic systems in 2016.3

  • Natural gas = 33.8%
  • Coal = 30.4%
  • Nuclear = 19.7%
  • Renewables (total) = 14.9%
    • Hydropower = 6.5%
    • Wind = 5.6%
    • Biomass = 1.5%
    • Solar  = 0.9%
    • Geothermal = 0.4%
  • Petroleum = 0.6%
  • Other gases = 0.3%
  • Other nonrenewable sources = 0.3%
  • Pumped storage hydroelectricity = -0.2%4
